Fallon was joined by special guests Andy Samberg and The Muppets, who led house band The Roots in a version of The Band's classic hit 'The Weight'.

The presenter joked during the episode: "You know, I'm really going to miss being on TV at 12:37. I'll especially miss the battle for late night ratings with my fierce rivals - Craig Ferguson and a veggie chopper infomercial."

Fallon more seriously took time to thank the loyal viewers that tuned in nightly over the last five years.

"Most importantly, I want to thank you guys. I want to thank the fans. I can't believe it," he told the audience. "This didn't exist five years ago.

"There was no such thing as this show five years ago. Isn't that crazy to even believe that? It means the world to me. You make me so happy. Thank you so much."
